HMIs: Real-time text labels overlaid on live video displays

Digital View has added a text overlay feature to its SVH-1920 Advanced High Definition LCD controller that merges video and informational text on a single display. Text sequences, delivered via the controller serial port, can be overlaid on up to four separate lines at the bottom of the screen. Using the company’s Serial Port Protocol (SPP), the controller can receive text strings up to 40 characters to display them in fixed locations at the bottom of the LCD screen. Text strings can be sent to individual lines, with horizontal positioning commands, line or screen erasure, and selectable background transparency. Applications include security displays showing active camera areas and other parameters, medical instrumentation displays showing real-time patient information. The overlay capability is customizable to provide formats or features for OEM customers.
